LOS ANGELES – Four years ago, Lindsay Lohan referred to Obama’s Presidential victory as “amazing,” but cut to 2012, and it seems the “Mean Girls” star has had a serious change of heart.

“I think unemployment is very important for now, so as of now I think (my vote) is Mitt Romney,” Lohan told reporters, including FOX411’s Pop Tarts, at the Mr. Pink Ginseng Drink Launch Party Los Angeles on Thursday night.

Lohan also hinted at mysterious underlying motives for supporting the GOP candidate and turning her back on Obama under wraps.

“It’s a long story, but you’re going to have to wait for that,” she remarked, adding that she would have liked to watch the Ryan vs. Biden debate, which had taken place just a couple of hours earlier, but for an unspecified reason, was unable to.

Last month, the troubled actress went as far as to tweet the President requesting he “cut taxes for those who need it: middle-class families, small businesses” as well as “those that are listed on Forbes as ‘millionaires’.” Perhaps her tweet was not granted.

Despite her support, Lohan hasn’t yet registered to vote, according to E! News.

Since Lohan moved from her previous home in Venice, she hasn’t registered and voter material mailed to her home was sent back, the Los Angeles County Voter Registration office told E!

Lohan has until Oct. 22 to register to vote in California, where she has her primary residence.
